What is the best use of Hacker News?

I'm new to this forum, learning the ropes here. I'm a book publisher that is always looking for innovative ways to teach my authors how to sell more of their books, and I have a specific interest in different forms of t-shaped marketing right now ... I think this is the way to go. But I'm looking for advice and guidance from bonafide growth hackers. Is this the right forum for that? Can you help me to help my authors better utilize the internet to sell more of their books?
